Thejas M Nair commented on HIVE-17426: -------------------------------------- I think we should make something executable only if it has been cleared to run in parallel. That way its going to be more resilient to bugs caused by future changes. +1 since other comments have been addressed. > Execution framework in hive to run tasks in parallel > ---------------------------------------------------- > > Key: HIVE-17426 > URL: https://issues.apache.org/jira/browse/HIVE-17426 > Project: Hive > Issue Type: Improvement > Components: HiveServer2 > Affects Versions: 3.0.0 > Reporter: anishek > Assignee: anishek > Fix For: 3.0.0 > > Attachments: HIVE-17426.0.patch, HIVE-17426.1.patch, > HIVE-17426.2.patch, HIVE-17426.3.patch, HIVE-17426.4.patch, HIVE-17426.5.patch > > > the execution framework currently only runs MR / Spark Tasks in parallel > when {{set hive.exec.parallel=true}}. > Allow other types of tasks to run in parallel as well to support replication > scenarios in hive. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
